A pregnant mom of two young girls died of her injuries after being struck by a car on Staten Island, officials said.

Shannon Lies, 31, left her job as a waitress at Mike’s Place Diner in Annandale a little early to get home to her daughters when a car going west on Hylan Boulevard hit her around 11 p.m. Monday, cops said.

“She just left work and was going to get the bus and got hit. She wanted to get home because she has two little girls at home. It’s a real tragedy for us,” said co-worker Fran Saccone.

Lies had been a devoted employee at the diner for 14 years and her co-workers said she was expecting a baby boy.

“She was a real sweetheart, a team player, she was happy to be here at work. She just buried her grandfather over the weekend. She was pretty upset about that,” Saccone said.

She died at Staten Island University Hospital South, officials said.

The 54-year-old driver continued for about a block before circling back to the scene, police sources said. The uninjured driver was not charged.
